No More Ply

[PJ Tiling]

I've been to price a job today and the customer has already bought all the materials for the job, on the advice of the supplier.

They have bought 'No more ply' to overboard the floorboards, which is pretty solid just a few areas to deal with. However I've never used NMP and I just wondered if there were any horror stories or things to avoid etc

 

[Gazzer]

Nope it is fine, use it all the time. Sometimes with the glue and sometimes with spf. Always over do the screws though.

 

[Ian]

In your opinion Neale, which is the better fixing method, SPF of the NMP adhesive?

 

[Gazzer]

T&G floor boards if they are worn or cupped then spf. Chipboard/ply or any other flat floor then the glue but dont get it on your hands...its evil stuff.

 

[Rookery]

I prefer Hardie + spf over NMP. I find NMP to be a bit brittle and the tubes of adhesive very expensive.

 

[John Benton]

Same as Neale, and he's right about the glue it's horrendous, but they do give you a pair of gloves to wear with every tube !!!

 

[Ian]

The thing that I can't get my head around with the glue is, there is hardly any contact if the instructions are followed. 2 rings of glue, surely all the voids are weak points?

Thats why I use spf if there will be voids. The adhesive they sell expands a fair bit so when yo put those 2 rings of adhesive on, it pays not to go too close to the edge of the boards as it will only come up through the joints.

I asked my suppliers about it today and they advised me to use 6mm ply instead, they didn't seem to believe in it.......and they sell it!

Still, customer has bought it. So see how I get on with it, always interested in using new materials

Just my opinion pj but if your supplier Is advising 6mm ply for over boarding, take everything they say with a pinch of salt

Thats being very polite ! :smilewinkgrin:

Majority of time I use SPF, but when the floor is flat then the glue is quicker and you can work on it very quickly

Yeah I do mate. Been using them for years, a lot of the advice they try give I don't agree with.

Thanks Sir Ramic picking up you guys termanologey

Well I used NMP for the first time today, not really a great deal of difference from hardibacker. Just as much of a pain to cut! The surface is much smoother than HB which I'm not sure if this is a good or bad thing, the grid pattern on HB gives a better key to the adhesive IMO. Also HB is a couple of quid per m2 cheaper. No doubting it is a good product and provides a nice substrate to tile to but, I won't be switching over from HB.

 

[Gazzer]

I find HB more expensive around here .

 

[Lee@emctiles]

Ive always found HBB more expensive.....

What is your normal price for HBB? What size Sheet?

 

[Gazzer]

Dunno its been a while but roughly same size as NMP. Only 2 places round here sell it.

 

[Ian]

NMP is 1.2x0.6 so 0.72 m2 and HB is 1.2x0.8 = 0.96 m2 and the same price per board.

 

[Lee@emctiles]

NMP is 1.2x0.6 so 0.72 m2 and HB is 1.2x0.8 = 0.96 m2 and the same price per board.

Hardie & NMP same price per board?? Really??

 

[Ian]

Ok, HB is 80p more per board but, there is 25% more board. It works out to be £2.13 cheaper per m2. Quite a difference over a big area.
